To all whom t may cof/wem .struction herein shown has in it some features in common with that shown in Letters Patent No. 1,376,191, patented April 26, 1921, in the name of Charles L. De Martin, William M. Matteoli and Samuel F. Arbuckle, which application was copending with this application.

The main object of this invention is to provide a lamp or headlight which will project the light or glare therefrom straight ahead, downwardly ,or to the side, as desired, and more particularly to the mountingA of a tilting reflector which may be controlle and tilted vertically or laterally at the will of the operator in positive. manner.

, Another feature of the invention is the construction of a dou-ble action tilting reflector headlight, whereby it may be` constructed and assembled in the most convenient and practical manner so that the various working parts are formed and held together so as to be readily demountable from the casing thereof. By means of this construction the reflector and all attached parts thereof for tiltably mounting it andv actuating it are formed in a single unit to permit its ready mounting or dlsmounting from the casing.

In the drawings, which are made a part of thisl application, Figure 1 is a vertical cross section through a lamp showing the tilted reflector mounted in the casing in position to project. the rays of light forwardly and parallel. Fig. 2 is the same as Fig. 1 showing the reflector in tilted posi-v tion for projecting the rays oflight forwardly and downwardly. Fig. 3 is a top plan view looking down upon the reflector with the upper portion of the casing removed, the reector being in position t0 Specification of Letters Patent.

project the rays of light-forwardly, either parallel. or downwardly. Fig. 4 is the sameA as Fig. 3 showing the reflector in position to project the rays of light laterally, either parallel or downwardly. Fig.' 5 is a section taken on the line 5 5 of Fig..1. Fig 6 is a section taken on the line 6--6 of Fig. v5.

In the vdrawings there is shown alamp casing 10 parabolic in form having a door rim 11 mounted thereon in which is secured a lens l2 inany suitable manner. The cas.`

ing 10 is provided with an outwardly extending peripheral llange 13 adapted to telescope within the rim 14 which is4 provided with a forward portion having a depression therein, in which a cord 15 ismounted for sealing the space between the lens 12 and said rim, and a rearwardly extending upper flange portion in which the peripheral flange 13 engages, whereby said rim 14 is securely fixed within the casing 10. Mounted upon saidrim there are spring hinge members 16 so positioned as to be 1n the vertical axis therethrough and provided with holes in their inner portion into which the pins 17 extend for pivotally hingingand securing` the ring 18 therein, whereby said ring 18 is pivotally mounted so as to swing laterally within the rim 14. The inner surfaces of the rim 14 and the ring 18 are nickeled so as to provide a reflecting surface in continuation of the reflector 19. The ring 18 is provided with a bow 20 'consisting of a metal strip fixedly secured to the periphery of said ring in the line of the vertical axis extending therethrough, and extending around and spaced apart and rearwardly from the rear of the parabolic reflector 19 so as to inglose said. reflector in a plane through its ver ical axis. The reflector 19 is hinged atits bot.

downwardly into tilting position, as shown 'in Fig. 2'under a constant. spring tension.

For overcomingsaid spring tension and returning the reflector to and maintaining it in its vertical position, as shown in Fig. 1, there is provided a fluid actuating means 24 consisting of a metal bellows which'contracts and pulls the reflector back into position by the suction produced from the intake mani- .fold of an internal combustion engine, not shown herein, upon the release of said suction, the spring 22 causing said reflector to be tilted forwardly, as shown in Fig. 2. The construction and o erating mechanism above described in whic the mounting of the reflector and .its operation is such that it may be controlled so as to project thelight parallel and forwardly, or downwardly and forwardly, as desired. v

Mounted upon the outer periphery of the rim 14', and' extending around the rear side of the reflector there. is a'strip 25 bent so as to form a ,lseat 26, and provided with a longitudinal slot therein through which a pin 27 mounted on the bow 20 extends so as to hold said strip. in position and permit lateral Swinging movement 'of the reflector, ring 18, and bow 20 upon the hinge pins 17, which movement will ermit, the reflector to project the rays of lght forwardly or i in..

laterally. 'For` actuating thefreflector vand causing it to swing to the position'sliown in Fig. 4 for projecting the rays .of light laterally, there is a metal vbellows 28 vsecured Aupon the seat 26 andconnected to the bow 20 so'that when it is contracted by the vacuum it will pull said bow laterally,

and said bowA being fixedly secured tothel ring 18 in which the reflector is mounted will cause said reflector'to swing on the pivot pins, as shown; `Said bellows r is connected up with the intake manifold lof the motor or an other suitable means not shown herewardly projected, as shown in Fig. 3 by means of a Spring 29 connecting the end of the strip 25 with .the bow 20.

4In operation, if the` driver of a vehicle desires to 'have` his light projectedat al distance ahead of him, he opens a valve which causes lthe bellows 24 to contract and hold thel reflector in the position shown in Fig.'

1, if he wishes the light rojected forwardly and downwardly, he t1 ts'` hisreflec-tor by closing the valve,l releasing the vacuum in the bellows 24 and ypermittm the spring 22 to tilt thereflector forwar if it is Idesired to swing 'the ra's of lightlaterally and .at a'distance ahea he operates both the belylows 28"and A24in a like manner so-as--tojy cause the reflector to Swingin the-position hereflecto'r is returned to its 'normal' position in which the rays 'of light are forv' first mentioned member is pivotally mounted for permitting the lateral turning of said member and reflector therein, an actuating means mounted between said first member and reflector for tilting the latter, and a second independently. mounted actuating means connectin said second mentioned member with sail first member for controlling thev movement within said first member.

2. A- lamp having a movable yreflector therein, a frame upon which said reflector is pivotally mounted, a second frame removably mounted' in said lam on -which said first mentioned `frame 1s pivotally mounted, actuating. means mounted within said first mentioned frame for adjusting the position ofthedeflector therein,`and a second actuating means mounted within said second .downwardly or laterally.

l. .In combinatinwith a lamp havinga casing `and a source of light therefor, of a single unit adapted to be "detachably lmounted within said casing,' including. a fixed rim, a movable ringV pivotally mounted withinv said rim,

a reflector lpivotally mounted within said ring, a bow secured on said ring and extending around said reflector, actuating means connecting said reflector and bow forv controlling the movement of said reflector in one direction, a

support on said fixed rim, and an actuating means connecting said support and bow for controlling movement of said movable ring for movin the reflector in another direction, .whereby t e-rays ofl light projected therefrom may be independently directed downwardly or laterally.` f
